It's a long story which I will try and keep brief.
ExH and I split almost 13 years ago. He had an affair and is married to the OW. I myself have been married to my DH for almost 10 years and I have no animosity towards ex over anything to do with the end of our relationship.
The 2 DC we have together are 17 and 14. Ever since we split Ex has treated me with nothing but contempt. He has been nothing but awkward and at times bullying. If he is getting his own way fine but if not he will not take no for an answer, will keep on and on trying to grind me down, will go back on arrangements/agreements and I have found this very draining over the past 13 years. Maintenance or lack of has also been an on off issue.
Almost 6 years ago Ex moved away from living locally to us. Up until then the arrangements for contact were that the Dc would spend every other weekend and one midweek night with him although he would more often than not call off the midweek contact.
When he moved contact reduced to the DC staying with him only a maximum of 3 times per year sometimes less and apart from birthdays he would generally not contact the DC between visits.
For the last 2 years DC 1 (17) hasn't been to stay with him at all. For a number of reasons:
- She has a part time job and her father only generally tries to arrange visits at the last minute (with the DC as he won't arrange anything through me) and it's always too late to let work down at the last minute.
- She's always made plans with her friends and feels she'll be missing out if she spends weeks with her father and changing her plans at the last minute.
- As her father doesn't contact either of them for months at a time and DD has said he's ignored her when she has text him, she feels like she doesn't know him, he doesn't know her and doesn't feel comfortable staying in his house.
As DD has gotten older she has increasingly become angry at her father for the lack of contact and seemingly only popping into their lives when it is convenient to him. He increasing won't take no for an answer when she tells him she doesn't want to stay with him to the point where she gets very stressed out and feels like he is pestering her.
She is also angry at her father for the way he treats DC2 (DS 14).
DS is desperately seeking his fathers approval. For all intents and purposes he feels like DD is favoured over him. The reasons why are that when Ex does make contact it's rarely with him just DD. Ex always makes sure DD's birthday card and/or present arrives in time but never does for DS. One year DS didn't receive anything for his birthday until 6 months later when it was DD's Birthday with no explaination.
DS feels that all of their fathers focus is aimed at DD also.
Poor DS has had a few meltdowns about this issue, the last one being so bad where he was sobbing to me "why doesn't my dad love me?" "Why is he never there for me?" "Why am I the least favourite?", he also said he hated his father but felt guilty for feeling that way and felt like a horrible person.
It absolutely broke my heart to see him in such a state and all I could do was try to reassure him that it's normal to feel different emotions and that he is very much loved.
After this I contacted his school who arranged for him to have some counselling.
Fast forward to 2 days before half term was due to start and Ex texts DD asking if she wants to stay with him over half term. She said no as she was working and had already made plans but as per usual he just kept pestering her not taking no for an answer. He really upset and stressed DD out as she had had exams all week and had a 5 hour practical exam the following day. She went to school really stressed out for her exam and hadn't had much sleep due to feeling so harassed by her dad.
I sent him a text to say that DD felt like he was pestering her and that she'd gone to school feeling upset and stressed out for her exam which wasn't fair and asked if he could call me to have a chat about the DC.
Up until that point I don't think we'd discussed the DC properly as he just won't speak to me about them and if we do ever arrange anything he just goes back on it.
He called and I politely told him how both of the DC felt. That he can't expect to maintain a proper relationship with them when he only has any kind of contact with them less than a handful of times in a year.
I said that DS felt like he was the least favourite to which he replied "I treat all of my children equally" (he has 2 more DC with his DW) yet when I asked him as to why he paid no maintenance towards his eldest 2DC he said he cannot afford it. This is despite leading a fairly luxurious lifestyle, nice cars, huge house etc 
Since I spoke with him he has done nothing but pester myself, and both DC saying he wants to speak with them. DD has refused point blank to speak with him, DS wants to but not on his own as he thinks it will be too awkward.
I suggested to Ex to give them some time and not push too hard especially DD who will dig her heels in. I suggested he get to know them again, dropping them a text once a week asking how their week has been, maybe making the effort to see them once a month, take them out for lunch that kind of thing.
That's not good enough for ex. He wants to speak to them NOW! Since DD has refused he's focusing on DS who doesn't want to either. He left a voicemail on my phone saying he doesn't want to leave it, wants to speak with DS face to face this weekend and and doesn't "see why it will be awkward, I am his dad after all".
I spoke to DS about having mediation with his dad and speaking to him that way if he doesn't want to do a face to face one on one with him, DS has agreed.
I spoke to ex this morning to explain that DS would like to talk with him through mediation, that I would contact his counsellor to see how I go about arranging something like that.
Ex got shitty with me but I'm trying my best.
15 minutes after we discussed the mediator he starts pestering DS again via texts about speaking with him this weekend and said "you can have your mum there if you like?".
DS hasn't replied but yet again ex has undermined me. I feel like I'm banging my head against a brick wall. I tried to explain to ex it's not about him it's about the DC and what they want to do but I think it's fallen upon deaf ears.
HELP I just don't know what to do.
